Appreciate the replies, I know the drive ain't bad but was looking into tank breakdown time(taking out fish,sand,water) then loading ,unloading,setup and fill. Probably gonna run over 2 hrs for the bigger tanks . I have battery pumps (a lot of them) but worried about the stress the fishes might experience. Would it be better to keep all filter,biowheels in a bucket of water with an airpump to help the BB?
